Based on your impressions of this upgrade, does it have you looking to upgrade the front sway bar in an effort to stabilize the car in corners even more?
From what I have read, if you do the front you need to further thicken up the back to compensate for understeer.
I'm looking for an ideal setup (obviously an objective measure without any real g-meters and testing, or skidpad results) that will maintain the front sway bar. Looks like it is tough to replace and requires garage work. Like you I have an eye toward doing most of the suspension upgrades myself.
I am also wondering what made you go with the 21mm bar over the STi 19mm bar.
Thanks in advance!
